Maryland Reverse Phone Lookup

Identify Phone Number Location Using Maryland Area Codes

To identify the location of an Maryland phone number, you need to understand the North American Numbering Plan (NANP) structure that all Maryland numbers follow: +1 NPA NXX XXXX.

• +1 - Country code indicating the United States
• NPA - The area code reveals the geographic region where the number was originally assigned
• NXX - Central office code that locates the specific neighborhood and identifies the service provider
• XXXX - Subscriber number identifies the individual phone line within that local exchange

The area code (NPA) is your key to determining location. By matching the three-digit area code to Maryland's regional assignments, you can identify which part of the state the phone number originates from. Each area code corresponds to specific cities and counties throughout Maryland, making it possible to narrow down the caller's general location.

Here's a complete list of Maryland area codes with major cities:

Maryland Phone Numbers

Maryland has approximately 9.2 million active phone numbers. Cell phones are the dominant type with 7.2 million users, while traditional landlines are much less common, with only 412,000 connections statewide. Internet phone services account for about 1.6 million numbers.

This breakdown indicates that searching a Maryland phone number will likely lead to a cell phone. The decline in landlines suggests that newer numbers may have less publicly available information compared to older landline numbers.

Other Maryland Phone Number Search Methods

Sometimes, a simple reverse phone lookup isn't enough to find out who owns a Maryland phone number. When that happens, trying a few different search methods can help you identify the owner, especially given Maryland's population of 6,263,220 and its 142,481 business establishments. These numbers mean that people and businesses can be hard to find, requiring multiple search approaches.

Social Media Phone Number Searches

Social media platforms can be useful for finding the owner of a Maryland phone number. For example, if you're meeting someone new and want to verify their phone number legitimacy, a quick search can help. Here's how to use social media to find a phone number:

• Facebook: You can try searching for the phone number in Facebook's search bar. Also, explore the Facebook public directory to see if the person has listed their number publicly.
• LinkedIn: If the phone number is associated with a business professional, LinkedIn can be helpful. With Maryland having 142,481 business establishments, there's a good chance the number is associated with a professional profile. Use the LinkedIn people directory and enter the phone number to see if it matches any profiles.

Maryland Business Phone Verification

If the phone number you're trying to identify belongs to a business in Maryland, verifying it through official state databases can be useful. For example, if you're considering business partnerships with Maryland companies, verifying their phone number is a good first step.

• Maryland Secretary of State: The Maryland Secretary of State website is a good starting point for verifying business information.
• Maryland Business Entity Search: Use the Maryland Business Entity Search to search for the business name or other details to verify the phone number and other business information.

For the best results, it helps to use these methods together.
